Data Highway Plus networks

The Data Highway Plus network is a local area network designed to support remote programming for factory-floor applications. The Data Highway Plus network lets you connect a maximum of 64 devices per link (although 15 or fewer nodes are recommended per link), including:

• PLC-5, PLC-3, and SLC 5/04 programmable controllers
• Color graphics systems
• Personal computers
• Host computers
• Numerical controls
• Programmable RS-232-C/RS-422 devices

You can configure a network of 99 links. With a multi-link network, you can have more nodes in the network. By placing nodes in the proper link with some nodes and separate from other nodes, you can also improve the efficiency of message delivery.

With A.I. 5 Programming Software, you can program your PLC controllers over your Data Highway Plus network. You can program a PLC controller from its local DH+ link or from a remote DH+ link in the network. This means that a single industrial terminal connected to your network can be used to program all the PLC controllers on all links of your network.

You can also use Data Highway Plus modules to implement a SCADA network.
